Seyg-El, also known in various versions as Jor-El I, is the father of Jor-El II as well as Zor-El and Nim-El and the former head of the Kryptonian Council. He's Superman and Supergirl's grandfather.

In Smallville, it has been stated that Jor-El does have a father and that he sent his son (Jor-El, as a young man) to Earth as a right of passage, in other words as a punishment.

Little is known about Jor-El's father, but we do know that he was the leader of the Science Council, until his death then his son Jor-El took control over the council.

He appears as an old man in the novel The Last Days of Krypton, as an old senile man at the end of his days, prior to the destruction of Krypton.
